"We come from a tradition in which knowledge has to be vouched for, authorized and approved by experts before it is allowed to reach us" (p.84). Wikipedia is a site where some information may be false rather than true. YOu have to be careful about using wikipedia because no one has authority over it- anyone can write and edit an entry, regardless of credentials. That is why wikipedia is not recognized as a good source for research by professors. It may be easy to access, but it is hard to check its validity.
